Rick Hillegas updated LUCENE-5471:
----------------------------------
Attachment: SecureLucene.java
Attaching SecureLucene.java, a program which shows this problem. To run the program, I put the program and the following jar files on the classpath:
lucene-analyzers-common-4.5.0.jar
lucene-core-4.5.0.jar
lucene-queryparser-4.5.0.jar
I see these successful results...
> java SecureLucene
Running unsecured...
Success!
Running with security manager...
Success!
...and this unsuccessful result...
> java SecureLucene true
Running with security manager...

> I see the following error when I run Lucene 4.5.0 under a java SecurityManager. I will attach a test program which shows this problem. The program works fine when a SecurityManager is not installed. But the program fails when I install a SecurityManager. Even more puzzling, the program works if I first run it without a SecurityManager, then install a SecurityManager, then re-run the program, all within the lifetime of a single JVM. I would appreciate advice about how to work around this problem:
